Just finished ICND 1 and 2 bootcamps and was building this lab during the first and second weeks of the course. I think it will do for now, but I'm on the CVoice, and CCNP track and have already paid the $11k for the schools.
Being a wireless engineer, and after taking a look at the CCNA Wireless objectives, I'm definitely adding that to the list of exams to take.

Question:
I have a few extra slots in the rack and was thinking of getting a voice router (2801?) and a few 7940's to practice. Also thinking about a Cisco 2509 to make access easier. What are your recommendations?
Lab Specs:
1 7100 Cisco VPN Router
1 2600 Cisco Router
2 2516 Cisco Routers
2 2900 Cisco Catalyst XL Switches
1 2950 Cisco Switch
1 400 Cisco FastHub
